Piston pin

The piston pin connects the piston to the connecting rod in the engine of a scooter or moped. This small but crucial pin ensures that the rotating movement of the crankshaft is converted into the up-and-down movement of the piston.

When choosing a piston pin, pay attention to the diameter and length, which must exactly match your engine's specifications. On this page, you will find piston pins for various engine types, including brands such as Yamaha and Polini, in a wide range of sizes.
